New Guinea Impatiens plant named ‘Ingrosab’

ABSTRACT

A new and distinct cultivar of New Guinea  Impatiens  plant named ‘Ingrosab’ characterized by its good branching habit with short internodes, medium sized dark green foliage, large light red-purple flowers with darker spot in the center, and good vigor.

Latin name of the genus and species of the plant claimed: Impatiens hawkeri.

Varietal denomination: ‘Ingrosab’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct New Guinea Impatiens plant botanically known as Impatiens hawkeri and referred to by the cultivar name ‘Ingrosab.’

The new cultivar was developed in a controlled breeding program conducted by the inventor in Enkhuizen, Netherlands. The new New Guinea Impatiens cultivar is medium sized with an early flowering response, large flowers with attractive coloration and a good flowering behavior under field conditions.

The new cultivar is propagated from cuttings resulting from the cross in September 2002 of the proprietary New Guinea Impatiens selection identified as ‘MM 221-1’ as female parent and the proprietary New Guinea Impatiens selection identified as ‘I 203-2’ as male parent. ‘MM 211-1’ is not commercially available and has not patented. ‘I 203-2’ is not commercially available and has not been patented.

As a result of this cross the present cultivar was selected in September 2003 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands, in Gilroy, Calif., and in Angers, France over a period of two years. The distinctive characteristics of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction. It takes 8 to 10 weeks to produce a finished plant, starting from a rooted plug and planted in a 12 cm pot, depending on the temperature.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Ingrosab.’ These characteristics in combination distinguish ‘Ingrosab’ as a new and distinct New Guinea Impatiens cultivar:

-   -   1. Large, flat, light red-purple flowers with a darker spot in         the center     -   2. Ball shaped plant habit with flowers on top of the foliage     -   3. Dark green foliage     -   4. Good basal branching character with short internodes     -   5. Good outdoor vigor

Plants of the new New Guinea Impatiens differ primarily from the plants of the female parent selection in the following characteristics:

Plants of the New Guinea Impatiens have large light red-purple flowers with darker spot in the center, whereas the plants of the female parent selection have rose flowers.

Plants of the new New Guinea Impatiens differ primarily from the plants of the male parent selection in the following characteristics:

Plants of the New Guinea Impatiens have large, light red-purple flowers with darker spot in the center, whereas the plants of the male parent selection have light red-purple flowers.

Plants of the new New Guinea Impatiens can be compared to plants of ‘Fisupnic Lipink,’ U.S. Pat. No. 16,118. In side-by-side comparisons conducted in Enkhuizen, Netherlands, plants of the new New Guinea Impatiens differed from plants of the cultivar ‘Fisupnic Lipink’ in the following characteristics:

-   -   1. Plants of the new New Guinea Impatiens have medium sized         leaves, whereas the cultivar ‘Fisupnic Lipink’ has large leaves.     -   2. Plants of the new New Guinea Impatiens have flat light         red-purple flowers with a darker spot in the center, whereas the         cultivar ‘Fisupnic Lipink’ has slightly cup shaped flowers,         light red-purple with a larger darker colored spot in the         center.

DESCRIPTION OF THE DRAWING

This new New Guinea Impatiens plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color showing being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new New Guinea Impatiens. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 30 week old plants, blossomed under natural light in the field.

Color readings were taken in the laboratory under ambient light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
